Abstract

Inventia se refera la un procedeu de obtinere a fibrelor acrilice cu proprietati îmbunatatile de antistatizare care în scopul mentinerii proprietatilor fizico-mecanice si a gradului de alb, se cofileaza doua amestecuri de solutii filabile avînd ca solvent solutii de 80-100% carbonat de etilena în apa amestecul I fiind un polimer acrilic de greutate moleculara 50000-80000, în concentratie 14-17%, la temperatura de 60-90 degree C, amestecul II un polimer acrilic de gr. moleculara 30000-60000, în concentratie de 6-1+% polimer acrilic si 6-10% negru de fum fin dispersat sub 0,5 niu la temperatura de 50-70 degree C, dupa care filamentele rezultate sunt supuse etirarii la un raport total de etirare de 1:5-1:7, iar dupa spalare, avivare, uscare, încretire se amesteca în proportie de 1....10% cu fibre acrilice normale.The invention relates to a process for obtaining acrylic fibers with antistatic improvement properties which, in order to maintain the physical and mechanical properties and the degree of whiteness, coalesces two mixtures of filable solutions having as solvents solutions of 80-100% ethylene carbonate in water mixture I being an acrylic polymer of molecular weight 50000-80000, at a concentration of 14-17%, at a temperature of 60-90 ° C, mixture II a acrylic polymer of gr. molecular weight 30000-60000 in a concentration of 6-1 +% acrylic polymer and 6-10% finely divided black carbon below 0.5 ° C at 50-70 ° C, after which the resulting filaments are subjected to a total 1: 5-1: 7, and after washing, soaking, drying, creasing mixed in the proportion of 1 ... 10% with normal acrylic fibers.
